Rohingya/Rohingya
language has been officially recognized and registered by ISO, International
Organization for Standardization, as being one of the world unique languages.
This official announcement has been done by SIL.ORG on its website ( http://www.sil.org/iso639-3/documentation.asp?id=rhg ) which says effective from July
18, 2007 Rohingya/Rohingya Language has been approved as an active individual
living language and hence assigned a unique identifier ISO-639-3 "RHG" as
being among the recognized Languages of the world. SIL.ORG is the official
site of the ISO 639-3 language Registration Authority and thus is the only one
authorized by ISO as stated in their website
( http://www.sil.org/iso639-3/default.asp
).

Also thanks to
Eng. Mohammed Siddique who, on 28 March 2007, has submitted comments
(
ftp://ftp.sil.org/iso639-3/cr_files/CurrentComments/2006-048_cm1.pdf )
about the development history of all our writing systems from Arabic
script to Hanif script to Rohingyalish script, and described the progressive improvements
achieved in each stage. Since Rohingyalish has got distinct superiority over
all others, he has requested ISO to recognize the Modern Rohingya
Writing System (Rohingyalish) and hence to assign an appropriate ISO code for
it. After more than 6 months of study over the issue, ISO has finally announced the recognition of Rohingya people, their
language and their modern writing system (Rohingyalish) on 18 July 2007 with
immediate effect. The final approval can be viewed with its approval stamp on
the first page, at SIL website link (http://www.sil.org/iso639-3/cr_files/PastComments/CR_Comments_2006-048.pdf ). The approval for the
language part was generally
based on his contributions to the Rohingya language website (
http://www.rohingyalanguage.com )
but particularly based on the article ( http://en.wikipedia.org/wiki/Rohingya_language
) contributed to the world famous online
free encyclopedia known as Wikipedia.
